Hi all,

I did a little experiment with photons, I wanted to check how the 
lighting was working with reflected light. I thought it was quite nice 
to look at.

I think it also shows well how photons work, and what photon_density is 
interesting for, the only thing you need to do is to look on the ground, 
at the light reflected by the cube (which is what we would expect, 
uniform and nice), and the light reflected by the cylinder (which has a 
strange look and some irregularities). This is due to the scattering of 
light rays on the cylinder.

Well, all of you probably already know that stuff, but i hope some (as 
me) didn't,   :-)

JC

Well that's a really pretty photons scene, but, as you may have guessed, 
most of us are used to these kinds of effects. I guess everyone has to 
start somewhere though, and I look forward to your future creations! :-)
